Primary Outcome Measures:
  • Indoor Tanning Behavior [ Time Frame: 12 months ] [ Designated as safety issue: No ]
    Self-report measure of the number of times the teenager has indoor tanned over 12 month time period. The self-report measure has been validated in previous studies.

  • Indoor Tanning Intentions [ Time Frame: 12 months ] [ Designated as safety issue: No ]
    A validated measure of the teenagers intentions to use indoor tanning in the next 12 months. Indoor tanning intentions are measured on a scale that ranges from 1 (definitely do not intend to indoor tan; better) to 7 (definitely do intend to indoor tan; worse).

  • Indoor Tanning Willingness [ Time Frame: 12 months ] [ Designated as safety issue: No ]
    Scale that measures adolescents willingness to indoor tan in the future. Indoor tanning willingness is measured on a scale that ranges from 1 (definitely not willing; better) to 7 (definitely willing; worse).

Arms Assigned Interventions
Experimental: Appearance-Focused Website Intervention
This is a Internet-based appearance-focused prevention intervention based on the Behavioral Alternatives Model.
Behavioral: Appearance-Focused Website Intervention
The intervention is a teen-friendly website with information concerning the health and appearance effects of indoor tanning.
Active Comparator: Control Website
Control participants viewed an Internet site designed to provide drug and alcohol education for teens.
Behavioral: Control Website
The control website contains information about alcohol and drug abuse which is oriented for a teen audience.

Detailed Description:
The project is designed to improve the understanding of, and ability to affect UV risk behavior in teenage populations. The International Agency for Research in Cancer classifies indoor tanning as "carcinogenic to humans." There is evidence that female indoor tanning use increases dramatically from freshman to senior years of high school (e.g., 25-40% of older high school girls) making high school a critical time period for anti-tanning interventions to be carried out. This proposal assesses the effectiveness of a skin cancer prevention website for a nationally representative sample of high school teens in a randomized controlled trial. Teens exposed to the website will report reduced indoor tanning intentions, frequency and overall percentage of users while increasing sun protective behaviors at long-term (i.e 18 month) follow-up.

Individual Participant Data  
Plan to Share IPD: Yes
Plan Description: The proposed research will include data from high school teenage women who indoor tan. The final dataset will include self-reported demographic, attitudinal, cognitive and behavioral data from surveys about private personal behaviors. The final dataset will be stripped of identifiers prior to release for sharing. We will make the data and associated documentation available to users only under a data-sharing agreement that provides for: (1) a commitment to using the data only for research purposes and to not attempting to identify any individual participant; (2) a commitment to securing the data using appropriate computer technology; and (3) a commitment to destroying or returning the data after analyses are completed.
